IMPROVEMENT IN UMBRELLA-SUPPORTS FOR VEHICLES.

Specification forming part of Letters Patent No.1 59,795, dated February16, 1875; application filed January 12, 1875.

To all whom it may concern:

Be it known that I, ALMON CLARKE, of Sheboygan, in the county ofSheboygan and State of WVisconsin, have invented certain new and usefulImprovements in Umbrella- Supports for Carriages and I do hereby declarethe following to be a full, clear, and eX- act description thereof,reference being had to the accompanying drawing and to the letters ofreference marked thereon.

My invention is intended as an improvement upon the umbrella-support forcarriages for which Letters Patent N 0. 123,380 were granted to meFebruary 6, 1872; and the nature of my invention consists in theconstruction of a clamp for the joint at the top of the standard, andalso in the mode of attaching the standard to the bed-plate, all ashereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, whichforms a part of this specification, and in which Figure l is a sideelevation of an umbrellasupport for carriages embodying my invention.Fig. 2 is an enlarged section of the joint through the line 00 00,Fig. 1. Fig. 3 is a plan View of the bedplate. Fig. at is a side view ofthe same. Fig. 5 is a section through the line 3 y, Fig. 3.

A represents the bed-plate, and B is the standard, with its foot 0fastened on the bedplate. At the upper end of the standard B is formedthe sleeve or socket D, in which the spindle E of the upright disk G isinserted. In the spindle E are countersunk a series of holes orrecesses, a a, in a circle around the spindle. b is a loose pin, theinner end of which is pointed and rests in one of the holes or recessesa. This pin passes through a boss, d, formed on the outside of thesleeve D, and which boss is provided with exterior screwthreads for thereception of a screw-cap, H. This cap surrounds and bears against theouter end of the pin 1), and holds its inner pointed end in one of therecesses a. By loosening the cap H the spindle E can be rotated ineither direction, for as the pin, when the cap is loosened, is no longerpressed inward, it readily clears itself out of the recess when thespindle is turned, and the pin is again pressed home to the bottom ofone of the recesses 60 by simply tightening the cap.

YVhen thus fastened the joint is perfectly secure and cannot work looseby the jarring of the carriage and the same device may be applied toother joints where needed.

On the surface of the bed-plate A are four projecting lugs, h h, forminga dovetailed tapering slide to retain the correspondingly'shaped foot 0of the standard. Between the lugs it on the surface of the bed-plate isan inclined plane, 1, the lowest part of which is toward the two lugswhich are nearest together. Through the foot 0 passes a short screw, a.provided with a long low head, m, to be out of the way of the cushion.This screw is in such a position as to impinge upon the incline plane t.Then this screw is tightened the foot 0 becomes very firmly fixed underthe lugs of the bed-plate, and loosening it liberates the standard, sothat it can be easily removed.

If the screw should become accidentally loosened a little the footcannot come out, as the inclined plane i will prevent the lower end ofthe screw from moving outward. This device may be used for other similarpurposes.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination of the sleeve D, having the threaded boss 61, theshank E,having recesses a a, the loose pin I), and screw-cap H,

all constructed to operate substantially as and for the purposes setforth.

2. The combination of the bed plate A, provided with lugs h and inclinedplane t', the foot 0, and screw m a, combined substantially as and forthe purposes set forth.

. ALMON CLARKE.
